  • Go to Microsoft account and select Sign in.
  • Type the email, phone number, or Skype sign-in that you use for other services (Outlook, Office, etc.), then select Next. If you don't have a Microsoft account, you can select No account? Create one!.Note that we recommend using an email you already have and use regularly.

SIGN IN TO GMAIL

Public or shared computers

If you're using a public or shared computer, be sure to sign out of your Google Account before leaving the computer. Learn more about signing in securely to Google.

hi.

Use Google Chrome as your web browser, then. On normal browsing mode, log into your 1st gmail account.

Then in google chrome, select "File -> New Icognito Window" and use the newly opened window for your 2nd gmail account. Works a treat.

Maybe you access your acc on another machine, that why is ask for.
So try this:
You may not want to sign out each time when using your own PC, but it is particularly important to sign out if you are accessing your account on a shared computer or public network. However, if you forget to log out, you can log out of all previous sessions the next time you are at a computer.
To do this, open your Gmail or Google Apps account and click on the Details link in the bottom right of your screen. This will open up a pop up window where you can see recent activity, whether your Gmail or Google Apps account is open in any other location, and choose to Sign out of all other sessions. Clicking that button will ensure all your previous Gmail and Google Apps sessions are logged out, leaving you logged in to the current computer only.

One of the following may be happening:

• You're not using the correct Google Account. Sign in with the Google Account you specified during the update process.
• You still need to update to a Google Account. Sign in with your DoubleClick username and password, or click the Update Now link to start updating your sign-in information.
• You're on the DoubleClick sign-in page instead of the Google sign-in page. Click theSign in with your Google Account link and enter your Google Account sign-in information on the page that appears.
• You're already signed in to another Google Account on this computer. You can be signed in to only one Google Account at a time. Sign out of the other Google Account, and try to sign in to your DoubleClick product again.
• In a few situations, you still need to use your legacy DoubleClick username and password.

Multiple sign-in is most convenient to use on devices that you don't share with other people (where you won't need to sign out to let others access their own accounts).

Sign in to additional accounts

1. Sign in to a supported Google product.
2. Click your name or email address at the top of the page.
3. Select Add account from the drop-down menu.
   
   
   
4. On the page that opens, enter the email address and password for another account you wish to access, and click Sign in.




Switch between accounts

Once you're signed in to more than one account in the same browser, you can easily switch accounts. Just click your name or email address at the top and click on the email address you'd like to sign in to.



Products that do not support multiple sign-in

Some Google products and mobile versions of Google products do not support the use of multiple accounts in the same web browser. Instead, they default to the first account that you signed in to from your current browser.
If you want to use an account with a product that doesn't support multiple accounts, you have two options:

• Sign out of all your Google Accounts and then sign in to the account you want to access.
• Sign in to another account using a second web browser Learn more.

Signing out

If you choose to sign out of any account while using multiple sign-in, you will be signed out of all your accounts. To resume using multiple sign-in, you will need sign in to one account and then use the Add Account option to sign in to your other account(s).
